3-Pin Microprocessor Reset Circuits

Description:

SSR809P/SSR810P are low-power microprocessor (μP) supervisory circuits used to monitor power

supplies in μP and digital systems. They provide applications with benefits of circuit reliability and low

cost by eliminating external components.

These devices perform as valid signals in applications with Vcc ranging from 6.0V down to 0.9V. The

reset signal lasts for a minimum period of 140ms whenever VCC supply voltage falls below preset

threshold. Both SSR809P and SSR810P were designed with a reset comparator to help identify invalid

signals, which last less than 140ms. The only difference between them is that they have an active-low

————————

RESET output and active-high RESET output, respectively.

Low supply current (1μA) makes SSR809P/SSR810P ideal for portable equipment. The devices are

available in SOT-23 package.

Features:

•

Ultra Low Supply Current 1μA(typ.)

•

Guaranteed Reset Valid to Vcc=0.9V

Available in Three Output Type: Open-Drain Active Low (SSR809N), Push-Pull Active Low

(SSR809P), Push-Pull Active High (SSR810P)

140ms Min. Power-On Reset Pulse Width

Internally Fixed Threshold 2.3V, 2.6V, 2.9V, 3.1V, 4.0V, 4.2V, 4.4V, 4.6V

Tight Voltage Threshold Tolerance: 1.5%

•

Tiny Package in SOT-23

Applications:

•

Notebook Computers

Digital Still Cameras

PDAs

Critical Microprocessor Monitoring

Typical application circuit:

• China - Germany - Korea - Singapore - United States •
